ADIAD8211WYRJZ-R7
Overview
The AD8211WYRJZ-R7 is an automotive-qualified, high-voltage current shunt monitor designed to amplify small differential voltages across a sense resistor. It features a wide input common-mode range of -2V to 65V and provides a buffered output voltage for direct interfacing with microcontrollers. This part is specifically engineered for high-side current sensing in systems where precision and high-voltage survival are critical.
Why Choose This Part
This monitor offers excellent DC performance with a typical 120 dB CMRR and a low 5 uV/degree C offset drift, ensuring accuracy over the full automotive temperature range. Its ability to handle negative input voltages down to -2V protects against common-mode transients and inductive kickback, while the AEC-Q100 qualification ensures reliability in harsh environments.
Applications
Key Specifications
Getting Started
To evaluate this part, use a high-precision, low-ohmic shunt resistor (typically 10-100 mOhms) matched to your expected current range. Ensure the 4.5V to 5.5V supply is well-decoupled and place the sense resistor as close to the IN+ and IN- pins as possible to minimize trace resistance errors. Evaluation boards like the AD8211-EVALZ are available for rapid prototyping.
